Big Idea:
Calculating profit is a way how much you earn and got. Profit helps people how much they have and how much they should have. Without the calculation of profit, people might have a hard time getting now how much they have

INV 3 Essential Question: How can I visually explain situations where one thing changes based on another? How can I use graphs, tables and symbols to solve problems?
I can visually explain situation on one thing to another by comparing the data by using graph or tables.

Notes;
*They charge 350$ to each customer but they have about 80$ profit as each customer increase.
*They have 80$ profit for each customer.
Question:


A. How much profit will be made if 10 customers go on the tour? 25 customers? 40 customers?

It will be $150 profit if 10 customers go on the tour. It will be $375 profit if 25 customers go on the tour. It will be $600 profit if 40 customers go on the tour.

B. How many customers are needed for the partners to earn $200 profit? A $500 profit? A $600 profit?

It would be 15 customers to earn $200 profit. It would be 34 customers to earn. It would be 40 customers to earn.


C. How does the profit change as the number customers increases? How is the pattern shown in the graph?

The pattern shows in the graph that as the number of customer increase the profit increase.

D. If the tour operators reduced their expenses but kept the price $350, how would change the graph

The graph would have a different look as the dots change its location in the graph but they are showing the same information. Either make it higher dot location for a higher profit scale or make it a lower dot location for a lower profit scale for each customer come to the tour.





F.U

In the profit graph, points at the intersection or two grid lines, such as (20,300) and (40,600), are easy to read. Use the “easy to read” points to figure out what the profit would be if only 1 customer went on the tour. How about 2 customers? 3 customers? 100 customers? Describe, in words, the estimated profit for any number of customers.

We can connect the dot with a line to show the information between the dots. We can continue the pattern of the graph until it reaches the information that we want. The answer is 15$ per customer.
